This image was taken during the Apollo 17 mapping metric sequence, revolution #14. The selenographic coordinates of this image are 18.50° N, 53.40° E.

The picture shows the western part of the Mare Crisium, a roughly lunar mare with a diameter of 418 km. The crater at the center of the image is named Peirce, while the smaller crater to the north is Swift. To the west of Perice, and concentric with the edge of the mare, is a wrinkle-ridge named Dorsum Oppel. Wisps of higher albedo material from a ray system can be seen scattered across the otherwise relatively dark surface of the mare.

This picture was produced by reducing a Hi-res image to 25% of full size, then rotating 90° counter-clockwise so that north is toward the top edge.
